WiiM Amp Firmware v5.0.630342 Update - Sep 24, 2024

I would never cross a sub above 100hz as it's just starting to get directional around that frequency

Not an issue with stereo subs (so far not supported by any WiiM product ).

After this update. The App search for the amp. Dint find the device. Then have to search manual for the device.

No such thing has happened on my amp. Have you already tried rebooting the device?

I have had something slightly similar, but not after this update. If it happens again, try turning off the WiFi on your phone, and then turn it back on, and then open the WiiM Home app, and in my case the missing device has reappeared.

Even I try this. Nothing happen

Please review the WiiM Amp update release notes below. If you encounter any issues, feel free to reach out to us.

5.0.630342 (In Progress)​

Release date:
9 / 24 / 2024

What's New:

1. USB Output (S24_3LE): Added support for S24_3LE audio format output via USB.
2. Plex Support (Beta): Integrated Plex for direct music access and playback in the WiiM Home app (iOS 2.11.6 required; Android support coming soon).
3. Playback Enhancements:
   • Fixed occasional no sound issues with Alexa Multi-room and Bluetooth Input.
   • Corrected metadata for custom radio stations and reduced cracking noise in some MP3 files.
   • Improved real-time playback after resuming from radio streams.
4. Advanced Subwoofer Controls (requires app version 2.11.7 or later):
   • Subwoofer Bypass Mode: Allows main speakers to output bass even when the subwoofer is active.
   • Full-Range Subwoofer Audio: Sends full-range audio to the subwoofer without applying a crossover
5. Graphic EQ Optimization: Reduced CPU usage for improved performance.

Bug Fixes:

1. USB Index Fix: Fixed missing metadata for certain WAV files and resolved an issue preventing complete music file scans on USB media.
2. Alarm Time Fix: Corrected rare incorrect alarm issue.
3. General Enhancements: Various bug fixes and performance improvements.

Try rebooting your router and the device

Maybe I misunderstand it but if you send frequencies even higher than 250 to the sub it will sound even worse. Subs aren't normally designed to work that high.
I can't try these new toggle switches as I am still on the beta firmware for independent channel room correction but get the feeling I am wasting my time as WiiM have stopped responding to any feedback about it.

Many/ most subs have their own crossover. Be it digital through it's own amp or through it's magical chain of resistors and capacitors. Mine is built to receive full range signal. That in no way implies it is going to output nor try to output that full range. My sub allows output up to 250hz. Not that I'm going to let that happen.

Anyway, this allows me to use my subs single purpose, well designed system to its fullest. It also allows me to ramp the crossover i.e. allow a certain degree of overlap of the main and sub. This all depends on the main speakers response and drop-off at said lower frequency.

I'm still experimenting and tuning. But I will say certain mid intense music ( like, Radiohead or Foals or We Were Promised Jetpacks) have certainly benefited. Those three I've just left to headphones until now. Just could never get them to sound right.

Yes I know subs have crossovers but the post I was replying to said to set the sub crossover to maximum.

The best subwoofers implement their crossovers about as good as a digital processor like the WiiM Amp can do it. Most are inferior.

All good subwoofers offer an LFE input, leaving all the filtering (except that required for safe and stable operation) to an external digital processor. Even if the name Low Frequency Effects seems to imply otherwise, this is in no way restricted to a HT environment. It's most useful for seamless integration of main speakers and subs.

Very few subwoofers implement high pass filtering for the main speakers. If they do, the cable routing is often a mess and flexibility is usually limited. High pass filtering the mains is the single most important aspect when it comes to improving their sound quality, in particular with 2-way designs. This is absolutely crucial and I don't understand why enabling Subwoofer Bypass Mode currently disables the crossover frequency slider.

It's right then (when you leave low pass filtering to the sub) that you need to be able to match the main speakers' high pass filter to the sub settings.

Admittedly, WiiM's bass management has been lacking some flexibility before. In certain situations it can be beneficial to set the high pass and low pass crossover frequency differently. Or even to chose different filter slopes. But this is much more rare than many might assume.

I would have preferred fully independent settings for sub and mains (optional) over the new toggle switches. These are probably easier to implement but still don't leave full flexibility amiss.

Just to point out, according to Wiim (early in this thread, the reason I came to it ) the Xover frequency is still active at the point set, tho greyed out. I hope that will change.

As to the 'all crossovers are the same or better on the Wiim' ... Well, if that works for you.... Also, the whole 'high pass filtering ' in the sub has nothing to do with what we're talking about. We're talking about full range at Line level to the sub. The mains are handled by the Wiim'.

It is still a ridiculous decision to grey it out though. To change the setting you need to take three actions instead of one. Which bright spark made that decision?

I don't see what you are after.

I just mentioned facts, not what works for me.

The greyed out frequency slider in SBM finally makes sense to me.
